Question

Two blocks of masses 2kg and 4kg are released from rest over a smooth inclined plane of inclination 30 degree. What is the normal force between the two blocks?

Answer 1

Answer:

Explanation:

=> According to the question, Two blocks of masses 2kg and 4kg are kept on smooth inclined plane. As inclined plane is smooth, we will not consider friction here.

=> Now, inclination of inclined plane is 30°

=> As the surface is smooth, accelaration of both blocks =  g*sin30°

= 10 * 1/2

= 5 m/s

=> that means both blocks move down with same acceleration. Thus  the normal force between the two blocks will be zero.
